Struggle with ATi 9200M

12-29-2008, 07:39 AM

Hi,

I have trouble getting my Mobility Radeon 9200 to work well with recent xf86-video-ati. Before v6.8 everything were autodetected and run fine. Since then the screen just go black. I manage to work around with option "CPPIOMode" "True". However with xf86-video-ati 6.9.0, laptop completely freez with black screen. Only way I found is to disable dri, but this result in very poor performance. I will appreciate any suggestion how to fix this. Also any optimized xorg.conf for this or close videocard is wellcome.
Computer is Sony VAIO PCG-K415S /Pentium(R) 4 CPU 3.06GHz/1GB RAM
Card ATI Technologies Inc M9+ 5C61 [Radeon Mobility 9200 (AGP)] (rev 01) with 64Mb VRAM.
Software is current Arch Linux i686, kernel 2.6.27.

AGPMode=1 work with dri enabled. It is a lot better now. I also try 2,3,4,6,8 which doesn't. Is there anything more I can do?

That should do it. Older versions of the driver used to default to the lowest AGP mode (1 or 4 depending on the AGP version). Newer versions of the driver default to whatever mode was set by the bios. The latter method has proven more reliable, but there are still cases where this doesn't work. Unfortunately AGP chipsets tend to be broken in various ways so it's hard to get it to work reliably in all cases. If you can pastebin your xorg log I can add a quirk to set the proper AGP mode for your card/chipset combo so you won't have to add the option in the future.
